IMPRO VEMENT IN ll?APBR-ZEIIEDEIRS.

' The Schedule referred to in these Letters Patent and making part of the same.

I, OLIVER NORELIUS, of'Minneapolis, in the county of Hennepin, and State of Minnesota, have invented an Improvement forFeeding Printing-Presses, of which the foliowing'isa specification, viz:

My invention relates to anew method of feeding paper to printing-presses by machinery. This-is done by a suction apparatus which, by the aid of a vacuum produced in a laterally-oscillating pipe, providedwith' a series of cups connected to and communicating with said pipe, from which the air is exhausted by a common air-pump, which causes one sheet of paper to adhere closely tothe mouth of the cups. time the movable table is caused to dropa little from the cups holding'the sheet. Then, to make-theoperation successful, another pipe is placed parallel-with the oscillating pipe, and is furnished with a current of air, and provided with several perforations opposite the table, from which currents of air passnnder the raised sheet of paper, passing backits whole length and separating it from the other paper lying on the table. Then the oscillating pipe moves forwa'rd,-and delivers the sheet to the gripers. At this instant the suction ceases and. the paper is released from the cups.

r Generol palm iption. A frame, A, supports, with suitable'bearings a a,

the printing-cylinder B, which hasa faceplate, 0, fast-- ened to one end of its shaft b.

An, eccentric pin, a, fastened to said face plate, im-

parts motion through a connecting-rod, D,to a cross lever, E, pivoted at e to a bearing, a, fastened to the flame A. One endof said cross-lever operates, with the pin '6, a piston-rod, f, of a force-pump, 1 The other end of-said cross-lever operates, with the pin a, a pistonstop-cock}; and connecting-pipe -Ic, \vith a reservoir or At this.

vacuum chamber, L, which is again-connected, through pipe I), with the vacuum pump G, p

- To facilitate the sucking up of the paper sheets, I provide the pipe H with a'number' of cups or short tubes, 72. h h It, which will lift one sheet of paper,

carry it-forward and deliver it to the gripers on he press. These said cups or tubes h h h" it have an inclined position while resting with the back edge on the paper, and the'front edge is up from the pape at an angle of about forty-five degrees. These cup --or tubes It h h h are brought in this position when in action to suck the top sheet from those, beneath, thus makin a space between the two sheets for the admission'o air from blowing-pipe F in front of table 'I.

I also lay a pipe, F, in front of the paper on the table I,- and direct, through-a number of small open ings, 1'', jets of air between the upper sheet (raised by' the cups) and the package below, whereby the upper sheet is separated through its entire length from those I beneath, and also kept partly suspended over theother sheets while'bei'ng drawn over to the cylinder, which makes that part work very easy. and removes all dan per bf tearing the damp sheets asunder. The pipe 1: receives compressed air from the pump F.

When the cross-lever E and pipe H are moved-intothe'position shown by dotted lines, the sheet which was taken along .by means described is released whendelirered to the gripei's on the printing machinery.

To effect this I -shut up the cock K with a. rod, k,

which acts on the eccentric pin It on pl'te K, forming a part-ofthe plug of cock K.

The rod it? receives its motion through two parallel levers, M M, pivoted, at 'm mfito the frame A, and

laterally connected by a link, in, which is pivoted tov them so that the motion of one lever necessitates a like motion of the other. The eccentric pin e on the revolving face plateO, with the described lever arrangement, produces and communicates to rod k? the movement-necessary'to open and shut the cock K with the properintervcning pauses.

A remarkable asslstance'is aiforded-for parting and drawing off the top sheet by the table I. This table is made to oscillatearound an axis parallel to that of the cylinder, and as soon asst sheet of paper is caught by the inclined cups oryshort tubes h 'h' h h, it'drops its. front end, and. leaves a space betweenthe upper shcetpand the next underone for the admission of air from the blowing-pipe F, and thereby assists the sepamt-ion of the top-sheet from the others.

To.efiect the described-dip of the table I, I fasten a lever, i, to it, which .is provided witlua segmental bearing, 1'', ,Below this a circular plate, N, with-a. small i ndentafion, n, ispiigotegl tc'thc frame A at mend is connected by an eccentriclpin n and link N with pivot a to a level", 0, which, is-pivot-ed to the frame -by a spring, 0, fastened to. it and the frame.

at 0,1and kept in contact with the surface of a cam,

" a The cam P is depressed at 11, while the other part cam P again, the plate N is infsuch position that. its

of it is-circularand concentric with its axis, and the revolution of .this cam, which is fastened to shaft '11,

creates an oscillating motion of ca'm N; This oscillation causes the circular part of the oath to come in contact with the friction-plates t" and communicate its own motion to it, thus giving to the table Ithe dc sired dip', as represented infig. 4 by dotted lines.

' \Vhen leverO bears on the depressed surface p of indentation n isparallel with the friction-plate i, thereby relieving thetable I, which resumes its original position, being slightly overhalanced at the back end.

When" the machine is to be operated, the paper is 7 put on table I with the 'front-ing edges at a suitable distance from pipe F. By action of the reyolvingfaceplate 0 andconnecting-rod Don the cross-lever E, the cups or short tubes h h h 7a are brought vin contact with thettop sheet of paper at the same time the cock K is opened, in the manner already described, the vacuumcha-mher L,-through the communications K K H H, immediately sucks the same sheet'upto the months of the tubes h h h h. a v

At this instant the table-I drops down and parts in before set forth;

thepaper sheets, leaving aspace between the t'op sheet and those beneath, and jets of air from the openings f .inJthe pipe'F are directed between the upper sheet and those below, the tableI remainingdown until the sheet is drawn ofi. a 1, i

As soon as the paper is brought over to the cylinder B, the suction inpipe'H'ceases by action of the cock K shutting oh the communication with the vacuum chamber L,and itis grasped by the gripersof the 'priuting press and there worked in the ordinary h manner.

Gl a t'ms. I claim as my in'vention Y 1; The combination of pump l and k, cock K, with itsmoving-gear'pipes'H-andH';

also pump F and pipe F, substantially as and for the purpose-herein before set forth; V

2. The combination ofithe'dipping table .I with friction-cam 1i, friction-plate N, connection N, lever O, and cam ,P, substantially, as and for the purpose herev OLIVER NORELIUS. Witnesses:
